Abstract

A safety lock system prevents unlocking of a balanced loaded unit when the loaded unit becomes unbalanced. A plurality of calipers applies pressure on opposite sides of a guide rail. A lock block couples the load to at least one of the calipers for movement of the load along the guide rail. A rotatable handle is coupled to the calipers through a shaft. Rotation of the handle locks or unlocks the lock block against vertical movement. A safety block is coupled to the loaded unit and is moveable with the loaded unit for preventing rotation of the handle upon a preselected movement of the loaded unit relative to the lock block.
